Merge sort stack overflow

Remember Me? Thread: stack overflow in merge sort of linkedlist. How can i solve it? After looking at the code for a few minutes I've realised that the problem merge sort stack overflow that your code for splitting the list up is not dividing the list evenly in two.

I'm using Linux merge sort sort -m to sort a large group of presorted files. I was assuming that merge sort would be considerably faster than a full sort on the unsorted data but that's not what I'm seeing.

Merge sort stack overflow

I am trying to write several different sorting algorithms in order to time the differences between them when reading a file of a half million integers. For testing purposes, I am only using a few hundred integers, but I am getting a stack overflow error. Also, for testing reasons, I have an output file being created during this run so that I can see if the code is working correctly. Originally, I had 3 nested for loops that I believed were causing the errors and horrible effeciencey , but I cleaned those up and I am still having the error. Can someone look this over and see if there is a glaring issue that I am overlooking. Thanks for any help you can give. I will also upload the. In this line you set the following interger to be a random number, where do you get this number from? This would therefore assume that the last value is at position - 1 what if the array contains only values? Would there be a position ? This is probably where your code is segmenting. You should also probably set the size of the array, i. So for example, I entered your values that you supplied and did the following:. Where we can assume that 0 is the first value inside the array and 99 is the last value, this printed out a result. Please see my attatched file.

Learn Python practically and Get Certified. Heap Sort is a popular and efficient sorting algorithm in computer programming. Learning how to write the heap sort algorithm requires knowledge of two types of data structures - arrays and trees. The initial set of numbers that we want to sort is stored in an array e. Heap sort works by visualizing the elements of the array as a special kind of complete binary tree called a heap.

Learn Python practically and Get Certified. Merge Sort is one of the most popular sorting algorithms that is based on the principle of Divide and Conquer Algorithm. Here, a problem is divided into multiple sub-problems. Each sub-problem is solved individually. Finally, sub-problems are combined to form the final solution. Using the Divide and Conquer technique, we divide a problem into subproblems. When the solution to each subproblem is ready, we 'combine' the results from the subproblems to solve the main problem.

Merge sort stack overflow

Merge sort is defined as a sorting algorithm that works by dividing an array into smaller subarrays, sorting each subarray, and then merging the sorted subarrays back together to form the final sorted array. In simple terms, we can say that the process of merge sort is to divide the array into two halves, sort each half, and then merge the sorted halves back together. This process is repeated until the entire array is sorted.

So, your 5 minutes running time just means that you've left the program running on an infinite loop for 5 minutes. Each function call adds a new frame to the call stack, which can cause the stack to grow too large if the recursion is too deep. Similar Reads. Suggest Changes. Here are some of the common applications of recursion:. The stack is a static and limited amount of memory to be used for local variables of functions as they are needed, it is not meant to be used to allocate large arrays like that. You should debug your code, find out where it is going wrong. Basic understanding of Recursion. Please go through our recently updated Improvement Guidelines before submitting any improvements. So, the base case is not reached. Replies: 6 Last Post: , PM. If you want to post a complete header, one that I can compile with fiddling around, I'll try it here and see what happens. My existing code currently all assumes an intrusive list, so it isn't as usefully templated as yours. Where we can assume that 0 is the first value inside the array and 99 is the last value, this printed out a result.

Following is a typical recursive implementation of Merge Sort.

Replies: 3 Last Post: , PM. A binary tree is said to follow a heap data structure if it is a complete binary tree All nodes in the tree follow the property that they are greater than their children i. Introduction to Hierarchical Data Structure. Reference Materials Built-in Functions. There may be more factors. You should debug your code, find out where it is going wrong. If instead, all nodes are smaller than their children, it is called a min-heap The following example diagram shows Max-Heap and Min-Heap. Note that the stability test isn't important, as it will sort just fine either way. Suggest changes. Check leap year.
